Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently handling cookie information, particularly in scenarios involving multiple browsers and encrypted traffic, leading to inefficiencies and privacy concerns, and lack of seamless integration with core network domains.
Innovation Solution
A method and apparatus for storing cookie information in the core network domain (CND) of a wireless communication network, associating it with a subscription, and managing it through a subscriber database, enabling secure and efficient handling across different browsers and encrypted traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cookie information is stored on user devices in traditional browsers, then user experience personalization is enabled, but privacy concerns increase and device resource usage increases
Solution Approach 1:
The patent extracts cookie information storage from the user device (browser) and relocates it to the core network domain (HSS database). This removes the privacy burden from user devices while maintaining personalization capabilities, as the network now manages cookie data centrally rather than distributing it across user browsers.
Solution Approach 2:
The core network domain acts as an intermediary between the content provider domain and user devices. Instead of direct cookie storage on devices, the network mediates by storing and managing cookie information in the HSS, enabling personalized service delivery without direct device involvement in cookie management.
2Adaptability or versatility
If multiple browsers are used on user devices, then browsing flexibility increases, but cookie management complexity increases
Solution Approach 1:
The patent merges cookie management across multiple browsers by consolidating storage in a single centralized location (HSS in the core network). Instead of managing separate cookies in each browser, all browsers access the same unified cookie store through the network, eliminating synchronization complexity while maintaining browsing flexibility.
Solution Approach 2:
The system enables self-service cookie management where the core network automatically handles cookie storage, retrieval, and synchronization across multiple browsers without requiring user intervention. This eliminates the manual coordination burden while maintaining flexibility in browser usage.
3Reliability
If cookie information is stored in the core network domain, then privacy is enhanced and device resources are reduced, but integration complexity with existing network infrastructure increases
Solution Approach 1:
The patent leverages the existing HSS infrastructure in 5G core networks, which is already designed for centralized subscriber data management. By repurposing this universal network component for cookie storage, the solution achieves privacy enhancement without adding separate dedicated infrastructure, thus reducing integration complexity.
Solution Approach 2:
The patent modifies the functional parameters of existing network elements (HSS, UDR) to include cookie information storage capabilities. Instead of creating new complex infrastructure, it changes the data parameters and storage functions of existing components, enabling privacy-enhanced cookie management through parameter evolution rather than structural complexity.
4Duration of action of stationary object
If cookie-based functionalities are maintained across encrypted traffic, then service continuity is ensured, but security risks may increase
Solution Approach 1:
The core network domain serves as a secure intermediary that handles cookie information management for encrypted traffic. By mediating between content providers and user devices through trusted network elements (HSS, PCF), the system ensures service continuity while maintaining security, as the intermediary controls and validates all cookie-related operations within the secure network perimeter.

AI summary
A technique for handling cookie information in a wireless communication network is presented. According to an exemplary aspect, a method of storing cookie information in a core network domain (CND) of the wireless communication network is presented. The method is performed in the CND and comprises receiving, from an entity in a content provider domain (CPD), a cookie handling request including identification information and cookie information, wherein the identification information is configured to be mapped on a subscription in a subscriber database and wherein the cookie information is configured to control execution of an application hosted in the CPD for a wireless subscriber device associated with the subscription. The method also comprises triggering storage of the cookie information in the CND and in association with the subscription.
